Using the Coil Inductance Calculator
Coil Geometry: Select the geometry of your coil from the list. You can choose from single-layer solenoid, multi-layer solenoid and flat spiral coil forms.
Length: Enter the coil length, measured as depicted in the diagram above.
Diameter: Enter the coil diameter, measured as depicted in the diagram above.
Depth: Enter the winding depth, as depicted in the diagram. This does not apply to a single-layer solenoid coil.
Number Of Turns: Enter the total number of turns.
Select Units: Select the units that you used for your coil dimensions from the list, and select your preferred output units of inductance.
